  Preservative options

  Posted by JanetJanet on July 31, 2018 at 5:38 pm

  Hi guys, 

  I have been making a facial serum using Vitamin B3 , B5 and Caviar extract with a natural preservative which only have a 4 months of shelf life. 
  Could you guys please recommend me a non-natural preservative for this serum that will have a longer shelf life for 1-2 years? My preference is something mild (no paraben) and safe for sensitive skin. 
  Or do you guys know where can i get these information? Any articles should i study on? 
  Will Perry’s course cover a list of preservatives and usage? Thanks!
